All bodies and discs shall be sufficiently ribbed to prevent body deflection. Body journals shall be designed to incorporate sufficient clearance and shall not incorporate internal shaft bearings or bushings, (when noted). Upper and lower body journals shall be drilled, tapped and plugged to accommodate purge lines when required. All bodies shall be stress relieved after fabrication. All welds to be full penetration. All valves shall be rated for PIG in the fully closed position or as required. : s shall be fabricated steel, split-shaft or through shaft removable construction and ribbed for maximum flow and minimal deflection. All discs shall be connected by means of solid taper pins securely fastened with retaining nuts or back welds. All discs shall be stress relieved after fabrication. will accommodate through shaft construction on high velocity applications. eat: All seats shall be located on the body and mechanically retained with removable retaining rings. The seat will be stepped to maximize the sealing surface and incorporate specified material. The seat material will be designed to withstand continuous service conditions and shall be field replaceable. haft: All shafts shall be split or thru-design. Minimum stainless steel or to meet the application and machined to accommodate direct mount actuation. haft diameters shall be to AWWA C-0 CL-B when specified by size. All shafts shall incorporate bi-directional thrust bearing and location locking collars. All shafts shall be supported by dual external roller bearings as required. All valves shall incorporate dual thrust bearings for 0 pipe orientation in vertical or horizontal pipe. Packing: Valves shall incorporate live loaded self-adjusting packing that is field replaceable without removal or disassembly of the valve from the piping for the application. Packing shall consist of minimum rings of Grafoil in each journal. Dual Packing will be used as required with external bearings. External Roller Bearings: All valve bodies shall incorporate upper and lower roller bearings to support the shaft and disc assembly. All bearings shall be permanently lubricated and field replaceable without the removal of the valve from the piping. Bearings shall be suitable for indoor and outdoor environments up to -0 F to 00 F or as required. All actuators shall direct mount to the valve shaft and mounting plate to IO standards. All valves shall be capable of mounting in any orientation in the pipe including the inverted position. Pneumatic Actuators shall be capable of mounting fail open or fail close in the field without changing actuator orientation when required. *Available at under uggested pecifications TJ ORDERING CHART of Construction Model TJ-A ize tyle W Body haft eat Packing Bearing Actuator ize tyle Wafer W F Wafer WF Weld Ends WE FP by plain end Carbon teel Titanium Aluminum pecial Packing ingle Teflon ingle Grafoil Dual Teflon Dual Grafoil ingle Adjustable Dual Adjustable pecial Bearing Delrin Acetal Duralon Internal External Roller Internal Dual Roller pecial Actuator Lever Gear Pneumatic DA Pneumatic R Electric (on/off) Electric (modulating) Hydraulic DA Hydraulic R Plain stem pecial A-Patton B-Titan C-Patriot D-Excalibur E-Helios F-pecial Body: : haft: eat: Carbon teel Titanium Aluminum pecial -PH Titanium Hastalloy pecial - Carbon - Titanium Aluminum EPDM Viton TFE Ceramic pecial 9 9 Above example part number indicates: a wafer style damper with a carbon steel body, carbon steel disc, shaft, metal seat (carbon steel) with dual Grafoil packing, dual external roller bearings and a double acting pneumatic actuator.
